Description

A New Type of Spinning Machine Baffle System

technical field

The invention relates to the technical field of spinning machines, in particular to a novel spinning machine baffle system.

Background technique

Spinning processing is a process in which the rotating material is squeezed point by point by a tool, and the material is deformed regularly and finally falls to fit the mold. Spinning processing is widely used in lighting, automobiles, furniture and other industries.

The baffle commonly used at this stage is erected on the same side as the knife, and a suitable round cake is selected as the baffle in combination with the size of the material. When ready, the system sends a signal to the solenoid valve, and the solenoid valve drives the cylinder to inhale air and drive the round cake to extend to the back of the material, without scratching the edge of the mold. At the beginning of spinning, the driving knife contacts the sheet to generate axial thrust, and the sheet falls to the mold and exerts an axial force on the round cake. Since the cylinder is in an inflated state at this time, the cylinder supports the round cake and acts on the knife. In the opposite direction, the lodging trend of the tablet is slowed down. The rotation of the material piece driven by the spindle will produce different linear speeds at the center and edge of the material piece. When the driving knife and the material piece exert force, the material piece will be deformed from the inside to the outside and form a wave-like amplitude. When the amplitude reaches the material piece After the edge, the amplitude will attenuate but not disappear, and a secondary amplitude from the outside to the inside will be generated-when the two amplitudes in opposite directions meet and the different driving sequences are superimposed, the material will become unstable. Wrinkles are formed accordingly.

In summary, the present invention designs a novel spinning machine baffle system.

Contents of the invention

Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new type of spinning machine baffle system, which enables the edge of the sheet to be supported early from the outside to the inside by external force, and is generated from the inside to the outside after the knife touches the sheet. The amplitude of the vibration is offset and attenuated under the action of the reverse supporting force, and the material is no longer affected by multi-directional forces, but mainly bears the axial force generated by the driving knife, and the material does not lose stability and does not produce wrinkled materials.

In order to achieve the above object, the present invention is achieved through the following technical solutions: a novel spinning machine baffle system, including a body, a main shaft, a main shaft belt, a motion platform, a movable hydraulic tail top, a baffle moving ring, The fixed ring of the baffle, the servo motor of the baffle and the screw rod, the two ends of the machine body are respectively equipped with a main shaft and a movable hydraulic tail top, the main shaft is connected with the main shaft motor through the main shaft belt, and the end of the main shaft is provided with a baffle moving ring, and the baffle moves The ring is connected with the fixed ring of the baffle through the moving coil fixed wheel, the fixed ring of the baffle is connected with the screw rod, the screw rod is connected with the servo motor of the baffle plate, and a motion platform is arranged on the body between the main shaft and the movable hydraulic tail top.

Preferably, the moving ring of the baffle is disc-shaped.

Preferably, a cross roller bearing is also provided on the rear side of the moving ring of the baffle.

2. In the spinning process, it is no longer necessary to use "turning the knife" and "returning the knife to press the mold", which greatly reduces the learning threshold for the use of equipment;

3. The friction between the blank and the disc can be ignored, the material can be well protected, and the appearance of the spinning part can be guaranteed;

4. The servo motor drives the screw to achieve precise control.

detailed description

In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

Referring to Figures 1-3, this embodiment adopts the following technical solutions: a new spinning machine baffle system, including a body 1, a main shaft 2, a main shaft belt 3, a motion platform 4, a movable hydraulic tail top 5, a baffle Plate moving ring 6, baffle fixed ring 7, baffle servo motor 8, screw rod 9 and moving ring fixed wheel 10, the two ends of the body 1 are respectively provided with a main shaft 2 and a movable hydraulic tail top 5, and the main shaft 2 passes through the main shaft The belt 3 is connected with the main shaft motor, the end of the main shaft 2 is provided with a baffle moving ring 6, the baffle moving ring 6 is connected with the baffle fixing ring 7 through the moving ring fixed wheel 10, the baffle fixing ring 7 is connected with the screw rod 9, and the screw rod 9 is connected with the baffle servo motor 8, and the body 1 between the main shaft 2 and the movable hydraulic tail top 5 is provided with a motion platform 4.

It is worth noting that the baffle moving ring 6 is disc-shaped.

In addition, cross roller bearings are also provided on the rear side of the baffle moving ring 6 .

When the knife squeezes the material, the round cake first supports the force-bearing side that is in contact with the knife. The deformation of the non-contact point is caused by the force point, which is a passive deformation, and there is a sequence. The baffle in the shape of a round cake can only provide good support for the material on the side of the stress point, and the material will shake due to uneven force, so that the material will wrinkle after contact with the driving knife. The introduction of the disk baffle in this specific embodiment supports the entire material, and the overall force on the material is more uniform and stable during high-speed rotation. For spinning processing, it means that in writing the tool rush program, the same processing effect can be achieved with fewer tool sequences; Return to the knife press mold", which greatly reduces the learning threshold for the use of equipment.

In this specific embodiment, a cross roller bearing is installed behind the moving ring 6 of the disc-shaped baffle, and the material sheet is deformed after being squeezed. At this time, the role of the bearing is that when the material is in contact with the disc, the disc will be driven by the material, and when the speed of the disc reaches or is close to the speed of the material, the friction between the material and the disc will increase. Can be ignored, the material can be well protected, and the appearance of the spinning parts can be guaranteed.

In the old baffle system, the electromagnetic valve is activated, and the cylinder sucks air to push the round cake out to stick to the material. When the cutter works, the material is squeezed, the round cake is pushed backward by the external force, part of the gas in the cylinder is discharged, and the rod body protruding from the cylinder is shortened. When the first part of the material has been applied by the knife, the solenoid valve will give a signal, the cylinder will exhaust, and the rod body will be recovered. The cutter continues its rushing process until the spinning process is completed. The new baffle system of this specific embodiment adopts a servo motor to drive the screw, and the support is realized in the form of connecting the screw to the fixed plate. The improvement of this part of the structure makes it possible for the disc to achieve more accurate positioning and more reliable support. Compared with the cylinder, the servo motor has better torque, that is to say, when the driving knife touches the material, it will push the disc backwards, but due to the existence of the servo motor and the screw, the force is not enough to push the disc to go step back. That is to say, this has completely changed the situation that the retreat position of the cylinder as a disc support is uncontrollable. Only need to write the position in the program, the servo motor can drive the extension and retreat of the fixed plate, and it can reach the orientation required by the process, which is a leap-forward improvement in the spinning process.

Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments.
